Websocket over SSL is very slow to compile

I'm writing and HTTPS server with WSS support. I've noticed that it's extremely slow to compile and generates a very bloated binary.
I've tried #including only what I need from both Asio and Beast but that makes no difference.
HTTPS on its own is fine. HTTP + WS is fine. But HTTPS + WSS is mega slow to compile (like 30s to compile a single file)
Anybody noticed this before?
@vinniefalco what's the state of https://github.com/cppalliance/http_proto and https://github.com/cppalliance/ws_proto ?
I imagine you eventually want to replace Beast with your suite of "sans-io" libraries that sit on top of Asio right?

The report names no files, tests, or minimal reproduction. Start by reproducing the HTTPS+WSS build described, comparing it with HTTPS-only and HTTP+WS, then inspect the Beast and Asio includes and the referenced http_proto and ws_proto projects. Done requires a confirmed explanation or actionable fix for the compile-time and binary-size regression.
